چکیده
BACKGROUND Chromosome 9p21.3 (chr9p21.3) recently was identified by several genome-wide association studies as the genomic region most strongly associated with the risk of coronary artery disease. Within the chr9p21.3 locus, the single-nucleotide polymorphism rs1333049 has been demonstrated to be most strongly associated with susceptibility to developing coronary artery disease. However, the effect of rs1333049 on clinical outcomes in patients with established coronary disease has yet to be determined. METHODS AND RESULTS Coronary Disease Cohort Study (CDCS) (n=1054) and Post-Myocardial Infarction (PMI) (n=816) study participants were genotyped for rs1333049. Clinical history, circulating lipids, neurohormones, cardiac function, and discharge medications were documented. All-cause mortality and cardiovascular hospital readmissions were recorded over a median follow-up period of 4.0 years for the CDCS cohort and 9.1 years for the PMI cohort. The CDCS patients homozygous for the high-risk C allele had an age of onset 2 to 5 years earlier for coronary disease (P=.005), angina (P=.025), myocardial infarction (P=.022), and percutaneous transluminal coronary angioplasty (P=.009). Patients with the CC genotype also had higher levels of total cholesterol (P=.033) and triglycerides (P=.003). The PMI participants with the CC genotype were 3 years younger on admission (P=.009). Cox proportional hazards analysis adjusting for established predictors of increased risk showed no significant association between rs1333049 genotype and mortality in either the CDCS (P=.214) or the PMI (P=.696) cohorts. CONCLUSIONS The chr9p21.3 polymorphism rs1333049 was associated with an earlier age of disease onset in 2 coronary disease cohorts but not with poorer clinical outcome in either cohort.

Polymorphism on Chromosome 9p21.3 Is Associated with Severity and Early-Onset CAD in Type 2 Diabetic Tunisian Population
Multiple association studies found that the human 9p21.3 chromosome locus is a risk factor for atherosclerosis. The purpose of this study was to investigate the association of the severity and early-onset of coronary artery disease with variant rs1333049 on chromosome 9p21.3 polymorphism and the impact of this variant on cardiovascular risk factors in type 2 diabetic patients. The study populat...
متن کاملChromosome 9p21.3 is Associated with Early-Onset Coronary Heart Disease in the Irish Population
Coronary heart disease (CHD) remains a leading cause of death across the world. A region on chromosome 9p21.3 has been recently reported to be associated with CHD. We evaluated 3 SNPs and 3 common haplotypes in the 9p21.3 region in 1494 individuals from 580 Irish families, where at least 1 member had early-onset (males <or=55 yr, females <or=60 yr) CHD. Genotypes were determined by multiplex SN...
متن کاملSocioeconomic Status Interacts with the Genetic Effect of a Chromosome 9p21.3 Common Variant to Influence Coronary Artery Calcification and Incident Coronary Events in the Heinz Nixdorf Recall Study (Risk Factors, Evaluation of Coronary Calcium, and Lifestyle).
BACKGROUND Genetic variants of a locus within the chromosome 9p21.3 region are consistently associated with coronary artery disease and coronary artery calcification (CAC). The aim of this study was to examine whether a 9p21.3 common variant interacts with socioeconomic status (SES) to influence CAC and incident coronary events in a population-based cohort. METHODS AND RESULTS 9p21.3 single n...
متن کاملLinkage of Parkinson’s disease in two very early onset siblings to a locus on chromosome 1
Parkinson’s disease (PD) is a prevalent neurodegenerative disease that usually affects individuals over 50 years of age. Age at onset in a small subset of PD cases is considerably lower, and these are considered early-onset PD (EOPD) patients. Most PD cases appear sporadic, but approximately 15% are familial, and some of the familial cases exhibit Mendelian inheritance. Genetic analysis of fami...
